Sun F77 compiler with Vax binary file Query

 Sun F77 compiler with Vax binary file Query

We have some programs written in fortran on a Vax which we have had to move to
a Sun Sparc running SunOS 4.1.3 . We have recompiled the programs but now find
that they dont work as expected. I suspect it is because they are working on
files which have been transferred from the Vax.
In the pollowing excerpt i am running one of the programs on the sun which
readds from a binary file which has been transferred from a Vax. It produces
the following error.

 occurred and were never cleared; see ieee_flags(3M):
 Inexact;  Underflow;
 Sun's implementation of IEEE arithmetic is discussed in
 the Numerical Computation Guide.

I have also had trouble with another program transferred to the Sun which reads from  an ascii file which
was created on the Vax by a F77 program. It gives the following error.

tigermoth 1> offconv
dofio: [-1] end of file
logical unit 2, named 'R15451.OFF'
lately: reading sequential formatted external IO
part of last data: -23     -23^?|
Abort (core dumped)

It looks as if there are extra characters after the last -23 in the above

Can anyone suggest what is going wrong in these two programs and how to fix
Any help will be greatly appreciated.
